I dont know about peaked, but I would say the window of opportunity for Dallas to have a legitimate chance at a Superbowl closed last season.
From 2016-2019, we had a young Dak on rookie contract, prime Zeke, 3 all pro lineman. Our defense was the weakness those seasons
From 2021-2023, I believe this we will look back on as Daks prime, while Zeke wasn't prime, the combo of him and Pollard gave us a pretty good running game. Still had two all pros on the line, the oline was still easily top 10. Dan Quinn gave us the most respectable defenses we've had in a while. We led the league in turnovers while he was here.
Now this year, how can anyone look at this team and say that it's anywhere close to competing for a Superbowl?
